OIL-PRESS.

SPECIFICATION forming part of Letters Patent No. 480,867, dated August16, 1892. Application filed September 28, 1891. Serial No. 407,008- (Nomodel.) Patented in France February 22, 1889, No. 196,157.

To aZZ whom it may concern:

Be it known that I, AUGUSTIN ESTRAYER, a citizen of the Republic ofFrance, and a resident of Marseilles, France, have invented certain newand useful Improvements in or Relating to Oil-Presses, (for which I haveobtained Letters Patent in France,No.196,157, dated February 22, 1889,)of which the following is a specification.

My invention relates to oil-presses.

The oil-press frame forming the subject of this invention is representedin the accompanying drawings, Figure 1 being a vertical section on linesab of Figs. 3 and 4; Fig. 2, a similar section on lines o dof Figs. 3and 4; Fig. 3, a a plan, and Fig. 4C a horizontal section, on line 6 fof Fig. 2. This frame or cage, the external shape of which iscylindrical, is supported on a base A, carried by four wheels B, adaptedto run on rails and enablingthe carriage so formed to be readily movedup to the oilpresses.

The internal shape of the cage, as shown in Fig. 3, is octagonal-i. e.,having two equal sets of four sides each. It consists of eight pieces ofsteel 0 D E F G H I J, the surfaces of which are plane or flatinternally and curved externally. These pieces, forming the verticalwalls of the cage or frame, may be brought nearer together by means ofinclines K, provided externally all around the apparatus. When themovable parts are moved close together, their contiguous surfaces 0, D,E, F, G, H, I, and J so fit each other as to form air-tight joints.These eight parts aresnrrounded by a cylinder L, also provided withinclines K, fitting against the inclines K, as shown in Figs. 1 and 2.The tightening or loosening of the eight movable parts is effected byraising or lowering this cylindrical casing L, which is provided forthis purpose with four screws M, Figs. 2 and 4, fitting four nuts N,having the shape of pinions, and as such operated by a toothed wheel 0,which in its turn receives motion from the worm P, operated by means ofa crank-handle Q.

This operation is as follows: To extract oil from oil-seed, the firstthing to be done is to loosen the parts or sections of the cage byraising the cylinder L, which for this purpose assumes the positionindicated in dotted lines in Fig. 1. This is done in order to removefrom between the walls, which are then moved apart, any residue theremay be left from the preceding operation and to introduce a fresh batchof material to be pressed. This material is placed upon the plunger of ahydraulic press, arranged to enter the cage from below. WVhen the cageis filled with material, the cylinder L is lowered and by means of thewedges K and K compresses the movable walls. These are provided at theirangleswith vertical grooves R, enabling the oil thus extracted to flowdown into the reservoir S, from which it is discharged by means of asuitable tap. Besides, to facilitate the flow of the oil as the oil-seedis compressed there are pro vided in the eight movable walls a number ofinclined or sloping channels T, arranged to discharge their contentsinto the grooves R, situated at the angles. To these channels areapplied vertical steel plates U, the upper and lower portions of whichare retained in place by means of other plates V. The plates U are setvery closely to each other and cover the whole interior of the case orframe.

Instead of raising or lowering the cylinder L by means of a screw,pistons or plungers, cams or eccentrics, or like devices may beemployed, and in other ways the invention be modified without departurefrom its essential features.

I claim- 1. The combination, with the cage or frame, of plates U and ofoblique channels T, terminating in vertical grooves R, for facilitatingthe discharge of the oil.

2. In an oil-press frame or cage, the combination, with the frame orcage consisting of a series of circumferentially-arranged sectionsadapted to be adjusted toward and from each other, as described, and anincline upon the outer surface of each of said sections, of a casingsurrounding the said movable sections and adapted for vertical movementthereupon, inclines upon the inner surfaces of said casing adapted tobear upon the inclines of the f rame-sections when the casing is moved,and means for operating the said casing, for the purpose specified.

3. In an oil-press frame or cage, the combination, with a base mountedupon supporting wheels, of the frame or cage mounted upon said base,consisting of a series of circumferentially-arranged sections adapted tobe adjusted toward and from each other, as described, an incline uponthe outer surface of each of said sections, a casing surrounding saidmovable sections and adapted for vertical movement thereupon, inclinesupon the inner surface of said casing,-adapted to bear upon the inclinesof the frame-sections, and means carried by the base for operating thesaid casing, for the purpose specified.

4. In an oil-press frame or cage, the combination, with a base mountedupon supportingwheels, of the frame or cage consisting of a series ofcircumferentially-arranged sections adapted to be adjusted toward andfrom each other, as described, an incline upon the outer surface of eachof said sections, a casing surrounding said movable sections and adaptedfor vertical movement thereupon, inclines upon the inner surface of saidcasing, adapted to bear upon the inclines of the frame-sections, andmeans carried by the base for operating the said casing, consisting ofscrews carried by the casing and extending through the base, toothednut: working upon said screws, a toothed wheel engaging the nuts, a wormengaging said toothed wheel, and a lever for operating said worm, asdescribed.

5. In an oil-press frame or cage, the combination, with a base mountedupon wheels and a reservoir in said base, of the frame or cage mountedupon said base and consisting of a series of circumferentially-arrangedsections adapted to be adjusted toward and from each other, asdescribed, and provided with a series of vertical grooves R,communicating with reservoir S, inclines upon the outer surfaces of saidsections, a casing surrounding the latter and adapted for verticalmovement thereupon and provided with inclines upon its inner surfaceadapted to bear upon the inclines of the frame-sections when thecasingis moved, and means for operating said casing, for the purposespecified.

6. In an oil-press frame or cage, the combination, with a base mountedupon wheels and a reservoir S in said base, of the frame or cage mountedupon said base and consisting of a series of circumferentially-arrangedsections adapted to be adjusted toward and from each other, asdescribed, and provided with a series of vertical grooves R,communicating with reservoir S, inclined channels T in said sectionsandcommunicating with the grooves R, inclines upon the outer surfaces ofsaid sections, a casing surrounding the latter and adapted for verticalmovement thereupon and provided with inclines upon its inner surface,adaptedto bear upon the inclines of the framesections when the casing ismoved, and means 1fior operating said casing, for the purpose speci- Intestimony whereof I have hereto set my hand in the presence of the twosubscribing witnesses.
